MABERRY L. DAVIDSON, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TOWILKINS BROS, OF MILFORD, NEW HAMPSHIRE, A FIRM.

BOOK.

Specification of Letters Patent.

Patented Dec. 12, 1905.

To aZZ whom it may concern:

Be it known that I, MABERRY L. DAVIDSON, a subject of the King of GreatBritain, and a resident of Boston, in the county of Suifolk and State ofMassachusetts, have invented new and useful Improvements in Books, ofwhich the following is a specification.

My invention relates to books, and particularly to that class of bookscomprising a cover or holder and a separable or removable pad or body ofleaves, such as are used for manifolding sales-books, blank notes, orsimilar purposes, in which the covers may be used again and again andthe pads or the like renewed when the leaves have been used up.

More specifically, my invention relates to books of this character inwhich the cover is provided with a holding device for a hook or tongueupon the removable pad or body of leaves. An example of a book of thissort is to be found in- United States Patent No. 647,933 for amanifolding sales-book and holder, in which a pivoted bail upon thecover cooperates with a tongue or corresponding bail upon the pad tohold the parts together.

The object of my invention is to provide a device which will admit ofassembling or detaching the parts more easily and expeditiously than hasheretofore been possible and in which the pad or body of leaves, whenthe parts are assembled, will be more securely held against thepossibility of accidental dislodgment than the devices heretoforeproduced. To this end I provide upon the cover of the book ahook-engaging member or pocket and upon the removable pad or body ofleaves a hook or tongue adapted to slip into the hook-engaging member orpocket, and so hold the pad or the like to the cover. To prevent thedislodgment of the 4 hook and the hook-engaging member, I prothe bookbeing open and the parts assembled. Fig. 2 is a section through the line2 2 of Fig. 1. Fig. 3 is a side view of the book, showing the method ofassembling the parts.

Referring to the drawings, 1 represents the holder or cover of the book,which may, as usual, be made of any suitable material, such ascardboard, leather, or cloth. The holder or cover may be singlethat is,it may be provided only upon one side of the bookor it may be doublethatis, it may embrace both sides-in which case the covers 1 and 2 areconnected by some suitable flexible material, as shown at 3.

4: represents a pad or body of leaves bound together at the edge in anysuitable manner, as by means of a binding-strip of cardboard or the likefastened over the edges of the leaves, as shown at 5. Upon the back ofthe pad 4: a hook or tongue 6 is provided, extending substantiallyparallel with the body of the leaves. This hook or tongue may be of anysuitable material and may be attached to the pad in any convenient way.An admirable form of construction is that shown in the drawings, inwhich the binding-strip 5 is extended beyond the threads or wires 7,which bind the strip 5 and the leaves of the pad together, so as to formthe tongue 6, which lies along the under side of the pad. To cooperatewith the hook or tongue 6, I provide upon the cover a hook-engagingmember or pocket 8. The movable stop to prevent the disengagement of thetongue and the engaging member is preferably in the form of a'plate 9,pivoted to the cover at 10 and yieldingly held in a vertical positionwith reference to the cover by coil spring'll. When in its normal andoperative position, plate 9 engages the edge of the pad, as shown inFig. 2, and prevents the tongue 6 from slipping out of pocket 8. When apad is to be removed or inserted, plate 9 is swung down substantiallyinto the plane of the cover, as shown in Fig. 3, out of the path of theedge of the pad. The hook or tongue may then be readily slipped into orout of hook-engaging member or pocket and the parts assembled orseparated. Plate 9 is then released and the spring llat once restores itto its normal position.

It will be clear that no particular form of stop or connection betweenthe stop and the cover is necessary, the only condition necessary to beobserved being that the stop shall [with said pocket; and a stop pivotedupon be adapted normally to prevent such movement of the pad as to causethe hook to slide in or out of the hook-engaging member and shall bemovable to admit of such manipulation of the pad. Neither is anyspecific form of hook or hook-engaging member required.

What I claim is- 1. A book comprising a cover; a movable pad or body ofleaves; a hook upon one of these parts; a hook-engaging member upon theother, cooperating with the hook; a stop pivoted to the cover andadapted, when in its vertical position with reference to the cover, toengage the edge of the pad or body of leaves and prevent thedisengagement of the hook and the hook-engaging member, and a spring forholding the stop in a vertical position while in use.

2. A book comprisinga cover provided with a hook-engaging member, amovable pad or body of leaves provided with a hook cooperating with thehook-engaging member, a stop pivoted to the cover and adapted, when inits vertical position with reference to the cover,

to engage the edge of the pad or body of leaves and prevent thedisengagement of the hook and the hook-engaging member, and a spring forholding the stop in a vertical position while in use.

3. A book, comprising a cover provided with a hook-engaging member; aremovable pad or body of leaves provided with a hook cooperating withthe hook-engaging member; a stop pivoted to the cover and adapted whenin its vertical position with reference to the cover to engage the edgeofthe pad or body of leaves and prevent the disengagement of the hookand the hook-holder; and a spring normally urging the stop toward suchvertical position.

4:. A book, comprising a cover provided with a pocket; a removable pador body of leaves provided with a tongue cooperating the cover near themouthof the pocket normally adapted to prevent the disengagement of thetongue and pocket and capable of movement to admit of suchdisengagement.

5. A book, comprising a cover provided with a pocket; a removable pad orbody of leaves provided with a tongue cooperating with said pocket; anda movable stop upon the cover near the mouth of the pocket yieldinglyheld in position to prevent the disengagement of the tongue and pocket.

6. A book, comprising a cover provided with a pocket; a removable pad orbody of leaves provided with a tongue cooperating with the pocket; and astop pivoted to the covernear the mouth of the pocket, yieldingly heldin a vertical position with reference to the cover, and normally adaptedto engage the edge of the pad or body of leaves and retain the tongue inengagement with the pocket.

7. A book, comprising a cover provided with a pocket; a removable pad orbody of leaves provided with a tongue cooperating with the pocket; aplate pivoted to the cover near and across the mouth of the pocket,adapted to be swung substantially into the plane of the cover or into aposition perpendicular to the cover; and a spring normally urging theplate into such perpendicular position.

8. In a book of the character described, a hook-engaging member adaptedto receive a hook upon a pad or the like; that pad, provided with ahook; and a springactuated movable stop normally adapted to engage oneside of the pad to prevent the disengagement of such hook and thehook-engaging member and movable against resistance of the spring toadmit of the insertion of such hook into, or the removal of such hookfrom, the hookengaging member.

9. In a book-cover of the character described, a pocket adapted toreceive a tongue upon a pad or the like, and a plate pivoted to thecover near and across the mouth of the pocket yieldingly held in aposition substantially perpendicular to the cover and in the path of theedge of such pad when its tongue is in the pocket, and movable out ofthe path of the pad to admit of the insertion of such tongue into or theremoval of such tongue from, the pocket.
